American Control Conference
作者: Raphael Louca Subhonmesh Bose Eilyan Bitar School of Electrical and Computer Engineering Cornell University Ithaca NY 14853 USA Department of Electrical and Computer Engineering University of Illinois Champaign 61820 USA
We derive a new upper bound on the minimum rank of matrices belonging to an affine slice of the positive semidefinite cone, when the affine slice is defined according to a system of sparse linear matrix equations. It ... 详细信息

Proceedings of the Seventeenth Computing on The Australasian Theory Symposium - Volume 119
作者: Alexandra Kolla James R. Lee Microsoft Research Redmond WA University of Washington Seattle WA
We present a simple construction and analysis of an Ω(log log N) integrality gap for the well-known Sparsest Cut semi-definite program (SDP). This holds for the uniform demands version (i.e. edge expansion). The same... 详细信息

IEEE Vehicular Technology Conference
作者: Chanfei Wang Tiejun Lv Hui Gao Anzhong Hu Key Laboratory of Trustworthy Distributed Computing and Service Ministry of Education School of Information and Communication Engineering Beijing University of Posts and Telecommunications
In this paper, two near-optimal detectors based on the convex optimization algorithm are proposed for multiuser detection (MUD) in the ultra-wide bandwidth (UWB) systems. The first detector performs semidefinite relax... 详细信息

Control Technology and Applications (CCTA),
作者: Diyou Liu Mohammad Khosravi Delft Center for Systems and Control Delft University of Technology Delft Netherlands
In this paper, we discuss the learning and discovery problem for the dynamical systems described through stable evolutionary Partial Differential Equations (PDEs). The main idea is to employ a suitable learning approa... 详细信息

IEEE International Conference on Signal and Image Processing (ICSIP)
作者: Fengyan Zhong Zhichen Li Chao Yang The Laboratory of Image Science and Technology Southeast University Nanjing China
In this paper, a high resolution raypath separation algorithm is proposed in the context of ocean acoustic tomography. By exploiting atomic norm theory, signals were sparsely represented in a two-dimensional continuou... 详细信息

Proceedings of the 30th Conference on Computational Complexity
作者: Massimo Lauria Jakob Nordström KTH Royal Institute of Technology Stockholm Sweden
We exhibit families of 4-CNF formulas over n variables that have sums-of-squares (SOS) proofs of unsatisfiability of degree (a.k.a. rank) d but require SOS proofs of size nΩ(d) for values of d = d(n) from constant al... 详细信息

SIGMETRICS 2010
作者: Takayuki Osogami Rudy Raymond IBM Research - Tokyo Yamato-shi Japan
We derive an upper bound on the tail distribution of the transient waiting time for the GI/GI/1 queue from a formulation of semidefinite programming (SDP). Our upper bounds are expressed in closed forms using the firs... 详细信息
